MY WITHDRAW FUNCTION

// Withdraw function
const withdraw = async () => {
  if (typeof window.ethereum !== "undefined") {
    const provider = new ethers.providers.Web3Provider(window.ethereum);
    const signer = provider.getSigner();
    const contract = new ethers.Contract(contractAddress, abi, signer);
    try {
      const transactionfund = await contract.withdraw();
      await listenedtotransactionmined(transactionfund, provider);
    } catch (error) {
      console.log(error);
    }
  }
};

Terminal showed this exception error of transaction reverted

I have an doubt that how will i get the address of the owner ..i think the owner is not withdrawing the money that exception error is being thrown

You are getting this error because you are withdrawing from the contract while being connect with an account that most probably didn't deploy the contract. Make sure that you connect to the contract using the same account that deployed fundme contract.

how will i get the owner of the contract.......?? i think the bug is that the withdraw function is not called by the owner of the contract

[othaime-en]

Did you deploy on localhost? If you did, and you have the hardhat-deploy plugin, then you can scroll upwards in the terminal running your node and you'll find the log of your deployments there. You can see what account deployed your contract there.

To resolve this, think of why FundMe__NotOwner is triggered--seemingly obvious.

modifier onlyOwner() {
        if (msg.sender != i_owner) revert FundMe__NotOwner();
        /// Alternative:
        /// require(msg.sender == i_owner);
        _;
    }

    constructor(address priceFeed) {
        s_priceFeed = AggregatorV3Interface(priceFeed);
        i_owner = msg.sender;
    }

Follows from the above, i.e. msg.sender

So, if you want the address you can just create a getter function for it
